When installing sale_margin, the computed fields will be computed on existing
sale.order and sale.order.line in database. On huge databases, the computation
may take a lot of time, depending on the configuration (multi-company, multi-currency, ...)
The current commit improves the computation of the purchase_price
(recently changed to a computed field), by avoiding unnecessary currency
conversions when possible (one less query to get the conversion rates).
In a multi-currency database where the products have no cost defined
(standard_price field), the sale_margin installation takes up to 50% less time.
